Endocrine System Part 1

 

Ratings

Overall Rating:

4.5 stars
Content Quality: 4.75 stars
Effectiveness: 4 stars
Ease of Use: 4.75 stars
Reviewed: Mar 30, 2014 by Biology Editorial Board
Overview: In 14 and ½ minutes, this slide presentation on YouTube gives an overview of the endocrine system: how it compares with the nervous system in terms of regulating body functions and the different classifications of hormones (this presentation limits the classifications to protein-based and lipid-based hormones). The video ends abruptly with a thorough description of how lipid-based hormones act on target cells. A marker is used to point out objects on the slide relevant to the narrative. A transcript is available. The narration is a female voice that is easy to listen to and comes across as very natural.
Learning Goals: Not specifically provided.
Target Student Population: high school and college (up through junior level).
Prerequisite Knowledge or Skills: The user should understand types of biological molecules and basic cell biology.
Type of Material: Presentation
Recommended Uses:
  • Can be used in class to enrich the learning experience
  • Can be recommended for supplemental use in the course outside of class as a study tool or review
Technical Requirements: Ability to play YouTube videos using any browser. A broadband connection is recommended.

Evaluation and Observation

Content Quality

Rating: 4.75 stars
Strengths:
  • Contents are clear and concise
  • Includes an adequate amount of material
  • Contents cover core curriculum within the discipline
  • Provides a complete demonstration of the concept
  • Integrates the concept very well
Concerns:
  • Presentation ends in the middle of a concept. It would be nice to have finished this presentation with action of protein-based hormones on cells
  • Some of the information is not current

Potential Effectiveness as a Teaching Tool

Rating: 4 stars
Strengths:
    The length of this allows it to be used to get across just a couple of learning objectives such as:
  • Definition of a hormone.
  • Principles of how the endocrine system functions
  • Compare and contrast neural and endocrine regulation of body responses.
  • Classes of hormones
  • Builds up on prior concepts
Concerns:
  • Does not identify learning objectives
  • Does not provide activities to reinforce concepts
  • Difficult to compare and contrast effects of lipid hormones and protein-based hormones which are in a separate presentation

Ease of Use for Both Students and Faculty

Rating: 4.75 stars
Strengths:
  • Easy to use
  • Self-contained
  • Presentation clearly designed
Concerns:
  • Not interactive

Other Issues and Comments: None.
